When MTV News caught up with Mim and Liv at Belgium's Tomorrowland music festival, they said they had already prepared plenty of pop-laced EDM to make sure the party doesn't slow down.

"We're going to be playing for quite a long time, I think," Mim said. "So it's a lot, a lot more records, which is really nice."

In addition to the music, the duo also had to make sure they had the best outfits picked out for their big night. The globally fashionable twins previously took to the trendy streets of Williamsburg, Brooklyn, in search of their perfect VMA looks.

"We have Red carpet outfits and also performing outfits, so I think that's the scariest thing about the night," Mim said.

Though we don't yet know what uniquely star studded ensemble the twins have in store, it's probably safe to bet that the crowd-pleasing, COVERGIRL trendspotters will show up #covermoment-ready as usual.
